Looks like it's a scale factor?
The base of the small one is 5ft and the base of the large is 45ft. If we divide
45/5 = 9
Since the height of the small is 40ft, we can multiply by 9, the number we just found, to find the value of X.
40 x 9 = 360ft

The value of s, which is the measure of the exterior angle, is 99°.
What is the exterior angle of a triangle?
An exterior angle of a triangle is an angle that is formed by extending one of the sides of the triangle. Specifically, it is the angle that is formed between that extended side and the adjacent side of the triangle that it doesn't share a vertex with.
In other words, if you choose one of the sides of a triangle and extend it, the angle that is formed between the extension and the adjacent side of the triangle is called an exterior angle.
Each of the three sides of a triangle has a corresponding exterior angle, and the sum of the measures of the three exterior angles of a triangle is always 360 degrees.
The sum of the measures of the exterior angles of any triangle is always 360 degrees.
In this case, we have two interior angles of the triangle given as s-50° and s-49°, and we are told that s is the measure of the exterior angle.
By definition, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles.
So, we have:
s = (s-50°) + (s-49°)
Simplifying the equation:
s = s - 50° + s - 49°
s = 2s - 99°
99° = s
s = 99°
Therefore, the value of s, which is the measure of the exterior angle, is 99 degrees.

According to a survey of 550 Web users from Generation Y, 297 reported using the Internet to download music. a. Determine the sample proportion.
b. At the 1% significance level, do the data provide sufficient evidence to conclude that a majority of Generation Y Web users use the Internet to download music? Use
the one-proportion z-test to perform the appropriate hypothesis test, after checking the conditions for the procedure.
a. The sample proportion is .54. (Type an integer or a decimal.)
b. What are the hypotheses for the one-proportion z-test?
Answers
The sample proportion is 0.54 (54%).
The hypotheses for the one-proportion z-test are:
Null hypothesis (H0): The proportion of Generation Y Web users who use the Internet to download music is less than or equal to 0.5 (50%).
Alternative hypothesis (Ha): The proportion of Generation Y Web users who use the Internet to download music is greater than 0.5 (50%).
At 1% significance level, you would then perform the one-proportion z-test to determine if there is sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.

edimentation tanks are often used as the first step in wastewater treatments. To make sure the entire water treatment process runs smoothly, we need to make sure that each step runs efficiently. In this wastewater plant, the sedimentation tank has a volume capacity of 17,000 m3. If a detention time of 3.4 hours is required, what should you have the flow rate set to in ML/day?
Answers
The correct answer is - the flow rate should be set to 14,444 ML/day to ensure a detention time of 3.4 hours is maintained.
Solution- 14,444 ML/day
Firstly, convert the tank capacity to litres since the flow rate will be in ML/day.17,000 m³ = 17,000,000 litres
The formula for calculating the flow rate is: Flow rate = Tank volume / Detention time
Flow rate = 17,000,000 litres / (3.4 hours x 24 hours)
Flow rate = 17,000,000 litres / 81.6 hours
Flow rate = 208,333.33 litres/hour
Now that we have calculated the flow rate in litres per hour, we can convert it to mega litres per day (ML/day) by multiplying by 24 and dividing by 1,000,000.
Flow rate = 208,333.33 litres/hour x 24 / 1,000,000 = 5 ML/day
Therefore, the flow rate should be set to 14,444 ML/day to ensure a detention time of 3.4 hours is maintained.

Converting the percentage to degree in the pie chart, angle PQ and UPT are 162° and 25.2° respectively
Pie ChartThis is a statistical tool used to represent data in a chart. It is often represented using angles or percentage.
To find the value of the respectively angles, we have to convert the values from percentage to degree.
The formula to do this is given as
Percentage = angle * (100 / 360)
A)
Angle PQ = ?
Substituting the values;
45 = angle * (100 / 360)
45 = angle * (5/18)
angle = 45 / (5/18)
angle = 162°
B) Angle UPT = ?
7 = angle * (5/18)
angle = 7 / (5/18)
angle = 25.2
The angle PQ is 162 degrees, the angle UPT is 25.2 degrees

Answer: Never(!) [assuming I understand/interpret the question properly]
Step-by-step explanation: The question wants to know how many months it will take for your neighbor's total cost be the same as yours, with three televisions. One has to interpret "total cost." I deem it to be the total accumulated costs, including installation. If you interpret it as the cost per month, then they charges are the same after the month the installation cast was paid. That's because the satellite provider charges per television, and 3*(13.32) is equal to the same 39.96/month charged by the cable provider. It the questions means total cumulative costs, the satellite customer will never exceed the cable customer's total bill, because of the installation fee ($75 for cable and free for satellite)
in a certain location of a highway, vehicle arrivals are poisson distributed with an hourly traffic flow of 210 veh/h. taking that into consideration, answer the following questions using 4 decimal places: a. what is the probability that the time headway will be less than 10 seconds? b. what is the probability that the time headway will be more than 9 seconds? c. what is the probability that the time headway will be between 5 and 8 seconds (inclusive)?
Answers
a) Probability that the time headway will be less than 10 seconds is 0.0228.
b) Probability that the time headway will be more than 9 seconds is 0.8737.
c) Probability that the time headway will be between 5 and 8 seconds (inclusive) is 0.2331.
(a) The probability that the time headway will be less than 10 seconds can be found by using the Poisson distribution formula and substituting λ = 3.5 (since the traffic flow is 210 veh/h, which corresponds to an average of 3.5 veh/min). Thus,
P(X < 10) = 0.0228.(b) The probability that the time headway will be more than 9 seconds is equal to 1 minus the probability that the time headway will be less than or equal to 9 seconds. Thus,
P(X > 9) = 1 - P(X ≤ 9) = 1 - 0.1263 = 0.8737.(c) The probability that the time headway will be between 5 and 8 seconds (inclusive) can be found by subtracting the probability that the time headway is less than or equal to 4 seconds from the probability that the time headway is less than or equal to 8 seconds, i.e.,
P(5 ≤ X ≤ 8) = P(X ≤ 8) - P(X ≤ 4) = 0.3159 - 0.0828 = 0.2331.Learn more about Probability:

Prove that: (Sec A- cosec A)(1+ tan A+cot A) = tan A× sec A - cot A × cosec A
Answers
Answer:
Step-by-step explanation:
\((sec A-cosecA)(1+tanA+cotA)=tanAsecA-cotAcosecA\)
we take the LHS so here goes,
\((sec A-cosecA)(1+tanA+cotA)=tanAsecA-cotAcosecA\\(\frac{1}{cosA} -\frac{1}{sinA})(1+\frac{sinA}{cosA}+\frac{cosA}{sinA})\\\\(\frac{sinA-cosA}{sinAcosA})(\frac{sinAcosA+sin^2A+cos^2A}{sinAcosA})\\\)
since , \(sin^2A+cos^2A=1\)
the identity becomes,
\((\frac{sinA-cosA}{sinAcosA})(\frac{1+sinAcosA}{sinAcosA})\\\\(\frac{sinA+sin^2AcosA-cosA-cos^2AsinA}{sin^2Acos^2A})\\\\\)
now, we know,
\(sin^2A=1-cos^2A\) and \(cos^2A=1-sin^2A\)
the identity becomes,
\((\frac{sinA+(1-cos^2A)cosA-cosA-(1-sin^2A)sinA}{sin^2Acos^2A} )\\\\\)
\((\frac{sinA+cosA-cos^3A-cosA-sinA+sin^3A}{sin^2Acos^2A})\)
sin A and cos A cancel out it becomes zero
\(\frac{sin^3A-cos^3A}{sin^2Acos^2A} \\\\\)
Splitting the denominator the identity becomes
\(\frac{sin^3A}{sin^2Acos^2A}-\frac{cos^3A}{sin^2Acos^2A} \\\\\frac{sinA}{cos^2A} - \frac{cosA}{sin^2A} \\\\\frac{sinA}{cosA}(\frac{1}{cosA})-\frac{cosA}{sinA}(\frac{1}{sinA})\\\\\)
Hence,
\(tanAsecA-cotAcosecA\)
